About the Rolls MB15b ProMatch
Connect your consumer and pro audio gear with this versatile 2-way converter
The Rolls MB15b lets you make clean connections between your consumer electronics and your studio recording or pro audio mixing gear. This 2-way box has two "channels." Channel 1 accepts professional line-level stereo XLR connections and outputs consumer line-level signals through its left and right RCA jacks. Channel 2 does the exact opposite, so you can convert in either direction. There's also an extra consumer line-level 3.5mm input and RCA aux output. Volume knobs for each channel let you dial in the signals for optimum performance.
